All proceeds from the charity single will be donated to the anti-gun violence organization.

Ben Platt and Lin-Manuel Miranda gave a heartfelt performance of their debut charity single, "Found/Tonight," during Saturday’s March for Our Lives rally in Washington.

During the rendition of the tune, a mashup of their previously recorded songs from both Hamilton and Dear Evan Hansen musicals ("You Will Be Found" and "The Story of Tonight"), the stars appeared visibly emotional while singing. Each of them donned "March for Our Lives" t-shirts.

After the performance, Platt and Miranda delivered words of encouragement to the teen activists. "We love you. Don’t give up," they told the crowd. As announced on the March for Our Lives Twitter account, all proceeds from the single will be donated to the organization.

Platt and Miranda are among the slew of stars who have expressed their support for the teen activists. Steven Spielberg and Kate Capshaw, Jeffrey and Marilyn Katzenberg, George and Amal Clooney and Oprah Winfrey have donated $500,000 each to support the cause. Jennifer Lopez, Jimmy Fallon, Lady Gaga, Nick Cannon, The Roots and others have also shared recorded messages to the teens, praising them for their efforts to make the events a reality.

Earlier this week, a letter penned by former President Barack Obama and former first lady Michelle Obama to the Parkland, Florida, shooting survivors was shared on Twitter via Mic, where they expressed how they feel "inspired" by the students' activism and commend their "awakening the conscience of our nation."

March for Our Lives events were set to occur Saturday in 847 locations worldwide, including Los Angeles, New York and Chicago.
